聚合切片器

GeneralSlicerData提供 aggregateData 函数来聚合列或区域的数据。

aggregateData(columnName: string, aggregateType: SlicerAggregateType, range?: ISlicerRangeConditional): number SlicerAggregateType 提供了 11 种类似 SUBTOTAL 函数的聚合类型: AVERAGE COUNT COUNTA MAX MIN PRODUCT STDEV STDEVP SUBTOTAL SUM VARS VARP 你也可以创建自己的数据聚合切片器,右侧为一个简单的数据聚合切片器用例示例。
